This is a case resolution report from the U.S. Department of Defense's All-domain Anomaly Resolution Office (AARO), dated February 6, 2025. It covers the January 2015 "Go Fast" infrared video that a Navy F/A-18F recorded off Florida. AARO worked only from the public video and found the object was at about 13,000 feet, not near the ocean surface, and moved at roughly 5 to 92 mph. The report attributes the apparent high speed to motion parallax and states with high confidence that the object showed no anomalous performance.
UNCLASSIFIED 14 UNCLASSIFIED value changes from 50 to 51, the value in that frame must be 51.0 (or 50.56) in that frame. These “change frames” were identified for the sensor azimuth, sensor elevation, and range to target in the time interval from t1 to t2 and are represented by the black dots in the plots in Figures 5-8. The values for all frames between 4239 seconds and 4252 seconds were estimated by fitting a 2nd order polynomial curve to the datapoints. These curves are the dotted lines plotted in Figures 5-8 and are generally a very good fit through the black dots. The fit equation and R2 fit error estimate are also provided. An R2 equal to 1 would be a perfect fit to the data. Figure 7: The sensor azimuth “change frame” data points are plotted vs frame time. The dotted line was fit to the points to estimate the azimuth for all frames in the time interval. 6 Whether the value is 50.5 or 51.0 does not make a difference as the times and positions are all relative and speed is found by subtraction. An uncertainty error of 0.033 seconds remains for each frame but is negligible here.
